Legal claims defining the scope of protection, as filed with the USPTO.
1. A touch screen system, comprising: a touch panel to input image signals; a touch controller to drive the touch panel; a printed circuit board mounted on the touch controller and including a plurality of connection pads connected with the touch controller; a flexible printed circuit connected with the touch panel and including a plurality of signal lines overlapping the plurality of connection pads of the printed circuit board; and an anisotropic conductive film electrically interconnecting the signal lines of the flexible printed circuit and connection pads of the printed circuit board.
2. The system according to claim 1 , wherein the printed circuit board includes a fixing guide disposed around the connection pads and contacting side portions of the anisotropic conductive film.
3. The system according to claim 1 , further comprising a liquid crystal module integrated with the touch panel system, wherein the connection pads of the touch controller are mounted on the printed circuit board.
4. The system according to claim 3 , wherein the printed circuit board is disposed at a rear surface of the liquid crystal module.
